Family kicked off a Southwest plane until the dad deleted a tweet calling the gate agent 'rude'

An incredulous passenger has said he will never fly Southwest Airlines again after being asked to leave a flight and threatened with the police unless he deleted a tweet that a gate agent did not like on Sunday.

To add insult to injury, marketing executive Duff Watson says that as an apology from Southwest they sent him three $50 vouchers after he became involved in an argument with the employee when he asked if his six-year-old daughter and nine-year-old son could join him as a priority boarder.

When the attendant declined to let his children on the Denver to Minneapolis flight first, Watson told her he was furious with the service and was taking to Twitter to complain about his family's treatment.
